There is a great deal of money to be made in telling people what they want to believe. In this case, you have one woman (and apparently others) who want to believe that they can learn to be safe in three easy lessons. It's silly, but no sillier than the many, many men (to judge by this and other forums) who believe that they need to learn to defend themselves from some kind of stereotypical attacker who is much more commonly found in comic books than on "the street". It's no sillier than a populace believing politicians who tell them that if they just sign on the dotted line, that war will be all over with in a matter of days and they'll be all safe and snug. Frankly, I don't look for self-proclaimed self-defense instructors to develop a sense of ethics when it comes to telling people the truth about safety until some time after politicians and leaders do the same.
